` CUSHIONING DEIICE'FOR PRESSING MACHINES.

Application led April 10, 1920. Serial No. 372,772.

To all whom z't may concern:

Be it known that I, ARTHUR E. SNOW, a citizen of the United States, residing at Norwood Station, Cincinnati, in the county 5 of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cushioning/Devicesfor Pressing Machines, of which the following is a specification.

This invention relates to cushioning devices for garment pressing machines. The object of the invention is to provide an improved cushioning device for relieving the shock ordinarily produced when the operating parts of the mechanism move toward open or release position, and particularly such a device which is automatic in operation, is simple in construction, can be readily applied to forms of press now in use,

and which does not interfere with or complicate other mechanisms of the press.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the drawings, Fig. 1 is a side elevation, partly broken out and in section, illusone form of press embodying the invention; Fig. 2 is a detail sectional elevation on the line 2-2, Fig. 1; and Fig. 3 is a detail sectional plan view on approximately the line 3-3, Fig. 1.

While the invention may be applied to any desired form of press the drawings show it applied to a press of the type illustrated in the Patent No. 1,311,311, dated July 29, 1919, to Charles L. Braley. Briefly described, the machine embodies a suitable frame 1 having an upright portion 2 in which is pivoted at 2a .a swinging arm 3 carrying an upper pressing member or head 4 which cooperates with the lower pressing member or bed 5. 6 represents a counterweight at the rear end of said arm and 7 a depending arm portion having cam surfaces 8 cooperating with antifriction members, such as rollers 9, upon one arm ofv an intermediate lever l0 pivoted at 11 in the frame. The front or depending arm 12 of said lever has a cam portion 13 for engaging an antifriction member or roller 14 upon the foot treadle l5 pivoted at 16 in the frame. 17 represents the release treadle mechanism and 18 one or more (two being shown) tension springs tending to move the parts to open or release position. Said springs terminate in or are secured at their lower ends to eyes 19 upon a cross shaft 20.

The cushioning mechanism forming thev subject matter of the present invention is designed for connection to and support upon the cross shaft 20. It includes a two armed lever or member 21 having a forward portion provided with a bottom cam engaging surface 22 and a rearwardly extending arm 23 provided with a hollow cup-shaped or socket member 24. In the chamber of said socket is a shock absorbing member 25 having a rounded head 26 which extends from said socket and engages the inner surface of the rear inclined wall 27 of the frame casting and which is also providedwith a shank 28. Said shank is surrounded by a compression spring 29 backed by a disc or washer 30 adjustable by the' set screw 31. The casting forming the lever 21 is quite heavy, its forward end being heavier than its socketed or rear end. Therefore, it has a natural tendency to tilt downwardly at the forward end. Its forward arm extends beyond the path of movement of the end portion of the arm 12, but to prevent it from dropping down in front of said arm suitable stop devices are preferably provided, such as a member 32 attached by the bolt 33 to l a suitable portion of the frame above the socket 24, the depending portion of said member being designed to be engaged by the socket member 24 and limit its movement.

Assuming the parts in the position shown in Fig. 1, when the release treadle mechanism 17 is actuated, the parts move to open or release position. Treadle 15 moves upwardly and the forward arm 12 of the intermediate lever 10 moves rearwardly, its cam surface 13 sliding beneath the surface 22 and raising the forward end of the lever 21. Lever 21 is engaged and operated near the end of the release movement, so that just before the press is fully opened the spring 29 is compressed and head 26 is dragged along the surface of the rear inclined castsuch that the rearwardly extending arm 23 and the spring pad or cushioning device is wedged, as it were, into the space between this wall and the pivot, thereby increasing the tension on the spring. Itis obvious that the cushioning or retarding effect is increased by this arrangement because there are two retarding factors, one being the spring resistance and the other the dragging action of the head 26 along the wall. Therefore, the cushioning mechanism described serves to soften the blow which otherwise is quite pronounced because of the heavy counterweight 6 and springs 18. The parts of the press are therefore relieved from shock and are more durable, while at the same time objectionable noise is overcome.

That I claim is 1. In a garment press, a frame having an inclined wall, a movable pressing member, mechanism for moving said member, a pivoted cushioning device having an operating part adapted to be engaged by the operating .mechanism and a cushioning part, a support for said cushioning device, said support being so located with respect to said inclined wall that the cushioning device is wedged between the support and said wall as the press opens. y

2. A garment press, comprising pressing members, a swinging lever Jfor actuating the same, and a yielding pivoted cushioning device having a portion lying in the path of movement of said lever to cushion the blow when the parts move to open the press.

3. The combination with a garment press embodying a frame, pressing members, and operating mechanism therefor, of a cushioning device, said device comprising a lever pivoted in said frame, one arm of said lever being adapted for operation by said mechanism, and the other arm thereof including a yielding device.

4. The combination with a garment press embodying a frame, pressing members, and operating mechanism therefor, of a cushioning device, said device comprising a lever pivoted in said frame, one arm ofsaid lever being adapted for operation by said mechanism, the other arm being provided with 'a socket, and a yielding-pressure member in said socket adapted to engage the frame.

5. A garment press comprising pressing members, a foot treadle, an intermediate lever actuated thereby and arranged to operate said pressing members, a yielding lever extending beyond the path of and adapted for operation by said intermediate lever, and means for preventing said yielding member from moving out of operative relation with said intermediate lever.

6. A garment press comprising pressing members, a foot treadle, an intermediate lever actuated thereby and arranged to operate said pressing members, a yielding lever adapted for operation by said intermediate lever, said lever being weighted for automatically returning it to idle position, and means for limiting such return movement of said yielding lever.

7. The combination. with a garment press embodying a frame, pressing members, operating mechanism therefor, spring means, and an anchoring shaft therefor, sald spring means having a normal tendency to open the press, of a yielding lever pivoted on the same axis as the anchoring shaft of said sprin means and adapted for operation by sai operating mechanism. f

In testimony whereof I ailix my signature.
